One day after her dislike of an orange jumpsuit stalled jury selection, the accused killer of “Realtor to the Stars” Linda Stein traded her jail gear for more proper courtroom attire — and the trial began.

Natavia Lowery, Stein’s former personal assistant, is charged with stealing the identity of, and killing, her high-powered boss.

Prosecutor Joan Illuzzi-Orbon yesterday told Manhattan Supreme Court Justice Richard Carruthers she wants to confront Lowery with a series of further allegations should Lowery try to portray herself as an honest employee.
